DUST-GUARD FOR'JOURNALvBOXES.

SPECIFICATION forming part of' Letters Patent No.- 701,629, dated June3, 1902.

Application filed December 28,1901. Serial No. 87,016. (No model) T0 at]whom it may conlcefin:

BERGER, a citizen of the United States, residing in Jacksonville, in thecounty of Morgan and State of Illinois, have .invented certain new anduseful Improvements 1 in Dust- Guards for Journal-Boxes, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification.

My invention relates to that class of dustguards used in railway-carjournal-boxes to inclose the car-axle journals and exclude dust from thejournal-boxes and also prevent the egress of'the lubricant andjournal-packing contained by the'box.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a View of one of the sheet-metal blanks from which thedust-guard packingholders are constructed. Fig. II is a perspective viewof my dust-guard. Fig. III is a vertical longitudinal sectional viewtaken through a journal-box aud my dust-guard therein. Fig. IV is avertical cross-sectional View taken on line, IV IV, Fig. III.

A designates the'journal of a car-axle, and B a journal-box containing adust-guard-receiving pocket 0. In my dust-guard a pair of counterpartpacking-holders are utilized to encircle the axle-journal and occupy thepocket in the journal-box B. The packingholders are constructed of sheetmetal formed from blanks illustrated in Fig. I, each holder having apair of side walls 1, provided with a semicircular recess 2, and alsoprovided centrally at their ends with semicircular recesses 3. At thecenter of each holder and extending longitudinally thereof between therecesses 3 is a groove 4. At each end of each packing-holder andprojecting'from the side Walls thereof are extensions that are adaptedto form flanges 5, that are bent toward the opposing side wall of theholder to inclose the packing within the holder and permit theprotrusion of guide-lips dbeyond said flanges, as seen in Fig. II. Theflanges 5 also serve to preserve the thickness of the packing-holders byholding their side walls apart by hearing against the lips 6. Theholders when formed up from the blank are held in shape by tongues 7,struck from the side walls of the holders and adapted to pass throughthe packing 10 in the holders and through apertures 8 in the oppositeside of the holder and clenched, as seen in Fig. II. 9 shows tonguesstruck from the side walls of the holders and adapted to enter thepacking 10 to serve as retainers for the packing. The packing 10 ispreferably of felt, though any other desirable material may be utilized,and each piece of packing is lsemicircularly recessed, as seen in Fig.II, to fit against the journal of the aXle to which the guard isapplied, as seen in Figs. III and IV.

11 designates a stirrup or yoke in which the packing-holders are movablypositioned and by which they are embraced. The guide-lips 6, projectingat each end of the holders at opposite sides, serve to direct themovement of the packing-holders within the pocket 0, so that they willride vertically therein within the stirrup 11.

12 designates a wedge-shaped cross-barhaving forked ends that are fittedto the stirrup 11 and adapted to fit snugly in the open upper end of thedust-guard pocket 0 to exclude the ingress of dust ordirt through theentrance to'said pocket. 1 The cross-bar 12 is provided with a centralopening 13, and passingthrough this opening is a fulcrum 14, that isadapted to seat in the groove 4 contained by the-upper packing-holder.The fulcrum 14*is provided at its outer end with a forked In thepractical use of the guard the pack-- ing-holders are placed one loelowand one above the axle-journal" in the dust guard pocket of the journal-box and mounted in the stirrup 11, the lower guard holder beingseated in said stirrup, with its groove 4 occupied by the lower end ofthe stirrup and the upper holder having its groove 4 occupied by thefulcrum 14, resting therein, as stated. The spring 16 acts centrally todepress the fulcrum 14, and its arms act to lift the yoke 11, therebycarrying the packing-holders toward each other and holding them firmly,yet yieldingly to the axle-journal, thereby producing a closure betweenthe exterior and interior of the journal-box.

I claim as my invention 1. The combination of a pair of packingholders,a stirrup holding said holders together, a two-armed spring providedwith a central coil and having a detachable connection with the ends ofthe stirrup, a fulcrum supporting the coil of the spring and bearingloosely against the upper packing-holder, and means holding the fulcrumagainst movement.

2. The combination of a pair of packingholders, a stirrup holding saidholders together, a cross-arm provided with a central opening, a fulcrumpassing through the central opening of the cross-arm, and bearingagainst one of the packing-holders, a twoarmed spring, mounted in thefulcrum and the ends of said arms engaging with the ends of thestirrups.

3. The combination of apair of packingholders, a stirrup holding saidholders together, a wedge-shaped cross-arm, provided with a centralopening, and forked ends which receive the stirrup, a fulcrum providedwith a forked head, passing through the central opening of thecross-arm, and bearing against one of the packing-holders, a twoarmedspring having a central coil, mounted in the forked head of the fulcrumand the ends of said arms engaging with the ends of the stirrups.

4. In a dust-guard, the combination of a pair of packing-holders,packing in said holders, guide-lips carried by said holders, inturnedflanges carried by said holders and adapted to bear against said lips,and means for embracing said packing-holders, substantially asdescribed.
